Abstract
Aminoplastic resin based on one or more amino derivatives and one or more aldehydes in which the amino derivative is melamine, glycoluril or their mixture in variable proportions and that the aldehyde is a product of formula (I) R--CHO where R=a dialkoxymethyl, 1,3-dioxolan 2-yl group optionally substituted on the vertex 4 and/or 5 by one or more alkyl groups or a 1,3-dioxan 2-yl group optionally substituted on vertices 4, 5 and/or 6 by one or more alkyl groups, optionally mixed with glyoxal, preparation process and use as a crosslinking agent for cellulose.
